Rotary milling.
Can it be done with some kind of special attatchment that’s fitted to the table of a bog-standard two-way-feed mill? I’m talking of a job like cutting a circular depression into a flat piece of work and then cutting a lip under the internal edge of the circle (for example).

The chuck would be handy, can’t think of anything right now I’d need the dividing plates for, and I don’t have a clue what the tail-stock would be for.
Just the same as on your lathe – To support long work on your rotary table when the table is mounted vertically.
You could use the tailstock and dividing plates to put evenly spaced flutes on a shroud or barrel.

Thats why I thought that one I posted was a really good deal. It is a 6″ though and would probably be to big for the smaller mills.
Grizzly has a 4″ that comes with plates for 153. The tailstock is extra.

I havent done it yet but for a chuck I figured I would just make adapters for the chucks off of my lathe and use those on the rotary table.
Dont forget your dividing plate, tailstock, 3 and 4 jaw chucks to go with it.
The rotary table is now on my list, I’ll order one tomorrow. Thanks chaps, you’ve been most excellent. 😀 😀 😀
I take it there are also circular ‘cookie-cutters’ for cutting out discs?
If you want to cut out a big hole…. you use either a boring head
You increase the offset (diameter) of the head with each pass… takes a while.
or a rotary table to cit the entire disk out which is quicker
(Or CNC…
)
I bought this rotary table. It has indexable plates and a tailstock included. He puts them on Ebay now and then. I paid 195 for it.

CNC, if only I had the moolah. 😥 😆
Yes, I’ve seen those indexers on various sites. Supposed to be for cutting cogs and the like. Didn’t think they could be adapted for other stuff, but human ingenuity… 😀
A dividing head is also useful for doing rotary work on a mill. bolt your work to the round table, and you can rotate the work piece. I put a 6 inch chuck on mine, you can cut any number of , equaly spaced, flats or groves down the length of a round shaft.

The dividing head also tilts.

CNC or rotary table will do that…. with a dovetail cutter if you want that angle on your shelf. If you just want a 90 degree angles then you could use a woodruff cutter.

Eee, that was exactly what I was envisioning! 😯 😆 That opens up almost endless possibilities. 😀
you can get a rotary table for $170. then grind down an endmill for the profile you want to cut.
